There is one clinical trial.
The study purpose is to examine polymorphism of genes associated to post-operative persistent pain and to verify the possible association between genotype phenotype and ADRB2 polymorphism in orthopaedic surgery. The primary aim is to evaluate the expression of ADBR2 in VAS>4 patients and to compare it to those with VAS<4.
Frequency of SNPs rs12654788 and rs1042713 of ADBR2 gene in patients who complain persistent pain 4 months postoperatively compared to chronic pain free patients.. null.
